The apical surfaces of hepatocytes are specialized to form the boundaries of the bile canaliculi. The canaliculi function to secrete and concentrate components of the bile and to transport the bile out of the interior of the hepatic parenchymal tissue to the epithelium-lined bile ducts.

Where are bile canaliculi found?
Bile that is produced by the hepatocytes drains into tiny canals called bile canaliculi (singular canaliculus). These drain into bile ducts located around the lobule perimeter.
What does the canaliculi carry?
Dental canaliculi are the veins of the teeth, which carry blood and nutrients from the pulp at the base of the tooth to the enamel.
What do hepatocytes do?
Hepatocytes, the major parenchymal cells in the liver, play pivotal roles in metabolism, detoxification, and protein synthesis.
Where are bile canaliculi located quizlet?
Where specifically are the bile canaliculi located? Bile canaliculi are slender intercellular spaces between neighboring hepatocytes.
What is the role of canaliculi in compact bone?
Each lacunae is connected to the others through a fine network of canals, called canaliculi. The canaliculi supply nutrients to the osteocytes, remove cellular wastes, and enable communication between cells. Finally, compact bone is covered by a double-layered membrane called a periosteum.
What structure of liver cell is Basophilic?
The nuclei and nucleoli of normal liver cells are small. Basophilic mate- rial is present in the cytoplasm of all cells. In this fixed material, it assumes various forms. In some cells, it appears as a diffuse blue staining of the cytoplasm-most often seen in cells near the portal connective tissue.
What is the function of hepatocytes quizlet?
protein synthesis, and Bile synthesis.
Do hepatocytes produce digestive enzymes?
Hepatocytes manufacture their own structural proteins and intracellular enzymes.
What is the function of the sinusoids?
The sinusoids are microscopic blood channels. The Kupffer cells are phagocytic, i.e., capable of ingestion of other cells and of foreign particles. They also store hemosiderin so that it is available for the production of hemoglobin, the oxygen-transporting component of the red blood cell.
Which hormone has a strong stimulatory effect on the gallbladder?
The actions of CCK binding to its CCK-B receptor have stimulatory effects on the vagus stimulation of gallbladder contraction. Emptying of bile is the result of four successive events.
What is portal triad in liver?
The portal triad contains the extrahepatic segments of the portal vein, hepatic artery, and bile ducts. ... The portal triad is contained within the hepatoduodenal ligament and contains the portal vein (posterolateral), hepatic artery (medial), and bile ducts (lateral) (figure 1).
What is the function of Diaphysis?
-Main shaft of longbone; hollow, cylindrical shape, thick, compact bone. Function: Provide strong support without cumbersome weight. -Both ends of long bone made of cancellous bone filled with red marrow.
Where is hyaline cartilage function?
Function of Hyaline Cartilage
When hyaline cartilage is on the articular surfaces of bones (the surfaces at joints), it is called articular cartilage. Articular cartilage functions as a shock absorber and also reduces friction between bones where they meet at joints.
Which structure is housed in canaliculi?
Osteons are cylindrical structures that contain a mineral matrix and living osteocytes connected by canaliculi, which transport blood. They are aligned parallel to the long axis of the bone. Each osteon consists of lamellae, which are layers of compact matrix that surround a central canal called the Haversian canal.
What are bile canaliculi in the liver?
Bile canaliculi also known as bile capillaries are thin tubes that receive bile secreted by hepatocytes. The bile canaliculi eventually merge and form bile ductules. The bile passes through canaliculi to the hepatic bile ducts and then into the common hepatic duct which drains directly into the duodenum.
Why do hepatocytes have microvilli?
The hepatocytes have many microvilli which project into this space, to increase absorption from the plasma. ... Hepatocytes synthesise and secrete bile into a system of tiny bile canaliculi which are present between adjacent hepatocytes.
Why do hepatocytes have two nuclei?
Multiple Nuclei in Human Cells
Hepatocytes, the cells found your liver, have a lot of jobs. ... Liver cells often have two nuclei so they can more efficiently do all these jobs. Having two nuclei is like having two sets of blueprints, so the cells can build two proteins at the same time.
